The invention discloses a method for measuring and acquiring body image data of a dairy cow in combination with multimedia image shooting and computer processing. In the method, the problem of body data acquisition of a dairy cow is solved by an image measuring method without contacting a dairy cow individual so that the stress reaction of the dairy cow to a stranger is avoided and damages of the dairy cow to measuring personnel can be prevented. Simultaneously, practical measurement of the image method is completed off line so that the time of a data acquisition process is much shorter than that of the conventional common manual measuring method. Moreover, the dairy cow moves little in a data acquisition period so that effect on a measuring result is small. The subjective factor of the conventional manual measurement has large effect on the measuring result while the image method is more objective and has higher data repeatability and correctness. Data obtained by the image method can be directly saved in a digital system in the form of database so that error caused by manual secondary input is avoided and contribution to digital management of a dairy farm is made.
